Jordan Pairs, E6 and U-Duality in Five Dimensions
Sergio Ferrara, Alessio Marrani, Bruno Zumino
By exploiting the Jordan pair structure of U-duality Lie algebras in D = 3 and the relation to the super-Ehlers symmetry in D = 5, we elucidate the massless multiplet structure of…
Freudenthal Gauge Theory
Alessio Marrani, Cong-Xin Qiu, Sheng-Yu Darren Shih +2
We present a novel gauge field theory, based on the Freudenthal Triple System (FTS), a ternary algebra with mixed symmetry (not completely symmetric) structure constants. The theor…
Charge Orbits of Extremal Black Holes in Five Dimensional Supergravity
Bianca L. Cerchiai, Sergio Ferrara, Alessio Marrani +1
We derive the U-duality charge orbits, as well as the related moduli spaces, of "large" and "small" extremal black holes in non-maximal ungauged Maxwell-Einstein supergravities wit…
Covariant Star Product for Exterior Differential Forms on Symplectic Manifolds
Shannon McCurdy, Bruno Zumino
After a brief description of the -graded differential Poisson algebra, we introduce a covariant star product for exterior differential forms and give an explicit expres…
Duality, Entropy and ADM Mass in Supergravity
Bianca L. Cerchiai, Sergio Ferrara, Alessio Marrani +1
We consider the Bekenstein-Hawking entropy-area formula in four dimensional extended ungauged supergravity and its electric-magnetic duality property. Symmetries of both "large" an…
Duality Rotations in Nonlinear Electrodynamics and in Extended Supergravity
Paolo Aschieri, Sergio Ferrara, Bruno Zumino
We review the general theory of duality rotations which, in four dimensions, exchange electric with magnetic fields. Necessary and sufficient conditions in order for a theory to ha…
